1. 系统：

2. JAVA安装

3. 安装jenkins

官网下载jenkis的rmp包，官网地址（http://pkg.jenkins-ci.org/redhat-stable/）——我使用了这个方法
wget http://pkg.jenkins-ci.org/redhat-stable/jenkins-2.7.3-1.1.noarch.rpm

rpm -ivh jenkins-2.7.3-1.1.noarch.rpm

网上其他推荐 添加Jenkins库到yum库，Jenkins将从这里下载安装

wget-O /etc/yum.repos.d/jenkins.repo http://pkg.jenkins-ci.org/redhat/jenkins.repo

rpm --import https://jenkins-ci.org/redhat/jenkins-ci.org.key

yuminstall-y jenkins

配置jenkins的端口（默认端口8080，如果不冲突可以不修改，netstat -ntlp查看已经占用的端口）

vi /etc/sysconfig/jenkins

4. 启动jenkins服务

service jenkins start/stop/restart

服务启动失败：Restarting jenkins (via systemctl): Job for jenkins.service failed because the control process exited with error code. See "systemctl status jenkins.service" and "journalctl -xe" for details.

解决办法：vi /etc/sysconfig/jenkins 修改JENKINS_USER="jenkins"  修改为JENKINS_USER="root"

再启动服务service jenkins start失败

Starting jenkins (via systemctl):  Warning: jenkins.service changed on disk. Run 'systemctl daemon-reload' to reload units.

Job for jenkins.service failed because the control process exited with error code. See "systemctl status jenkins.service" and "journalctl -xe" for details.

解决办法：vi /etc/rc.d/init.d/jenkins 增加java路径（路径查看：which java）

再次启动服务，ok

5. WEB访问，http://IP:端口号

出现无法访问此网站，检查代理服务器和防火墙

解决办法: 关闭防火墙

systemctl stop firewalld.service #停止firewall

systemctl disable firewalld.service #禁止firewall开机启动

6. 访问成功后输入密码，根据提示地址查看，输入后可登录成功
